🔄 How It Works

The rankings are automatically updated daily via GitHub Actions:

1. Data Collection: Fetches certification data from Credly API for all countries worldwide

   • Collects GitHub certifications from official GitHub organization badges
   • Includes Microsoft-issued GitHub certifications (migrated from GitHub in 2024)
   • Uses parallel processing for fast data retrieval
   • Optimized handling for large countries (India, USA, Brazil, UK)

2. Fair Ranking Criteria: Ensures an equitable competition

   • Position-based ranking: The ranking shows 10 positions, not 10 users — professionals with the same number of certifications share the same position
   • Expired certifications are excluded: Only active, valid certifications count
   • Excluded certifications: Badges that can no longer be earned (e.g., GitHub Sales Professional) are excluded to keep the competition fair
   • Duplicate prevention: Same badge name counts only once per user
   • Top 50 candidates per country are validated for accurate results

3. Multi-dimensional Rankings: Each regional ranking includes

   • 🏆 Top 10 Professionals — Individual ranking by certification count
   • 🏢 Top 5 Companies — Companies with the most certified professionals in the region
   • 🌐 Top 5 Countries — Countries leading in certifications (excluded for single-country rankings)

4. Company Information: Enriches rankings with professional context

   • Company data fetched from public Credly user profiles
   • Displayed alongside name and certification count in rankings

5. Data Storage: All certification data in the datasource/ directory

   • Individual CSV files per country (e.g., github-certs-brazil.csv)
   • Metadata tracking for update timestamps and optimization

ℹ️ GitHub Certifications Sources

This project tracks GitHub certifications from two sources:

1. GitHub Organization Badges - Certifications issued directly by GitHub on Credly

   • Core Certifications: Foundations, Actions, Advanced Security, Administration, Copilot
   • Partner Credentials: Migrations, AzureDevOps Migrations, Advanced Security Partner Delivery
   • Any other active badge issued by the GitHub organization

2. Microsoft-Issued Badges - GitHub certifications transitioned to Microsoft Learn

   • GitHub Foundations, Actions, Advanced Security, Administration, Copilot (Microsoft Certified)
   • Microsoft Certified: DevOps Engineer Expert
   • Microsoft Applied Skills related to GitHub

Note: As of 2024, GitHub migrated some certification issuance to Microsoft Learn. Certifications that can no longer be earned (e.g., GitHub Sales Professional) are excluded from rankings to ensure fair competition.

🎯 Ranking Fairness

• Position-based: 10 positions shown — tied professionals share the same rank
• Active only: Expired certifications are automatically excluded
• Excluded badges: Certifications no longer available for earning are not counted
• Daily Updates: Rankings refresh daily to reflect newly issued and expired certifications

🛠️ Technical Details

Data Source

Data is sourced from the Credly API for GitHub certifications.

Performance Optimizations

• Intelligent Candidate Selection: Fetches detailed badge data only for top 50 candidates per country
  • Reduces API requests by ~95% for large countries
• Parallel Processing: Fetches multiple countries simultaneously using ThreadPoolExecutor
• Metadata Tracking: Skips recently updated countries to reduce unnecessary API calls
• Specialized Handlers: Large countries use optimized parallel page fetching
• Smart Caching: CSV files stored with timestamps for efficient updates

Certification Validation

• Expiration Checking: Each badge's expires_at_date is validated against current date
• Dual Source Tracking: Combines GitHub org badges + Microsoft external badges
• Excluded Badges: Certifications no longer available (e.g., GitHub Sales Professional) are excluded via EXCLUDED_BADGES
